7. How can you convert a fraction to a decimal?

Multiply the numerator by the denominator.

Divide the numerator by the denominator.

Add the numerator to the denominator.

Subtract the numerator from the denominator.

To convert a fraction to a decimal, you divide the numerator (the top number of the fraction) by the denominator (the bottom number of the fraction). This process is based on the concept that a fraction represents a part of a whole, and by dividing the numerator by the denominator, you determine how many times the fraction represents the whole. The result of this division is expressed as a decimal. For example, if you have the fraction 3/4, when you divide 3 by 4, you get 0.75, which is the decimal equivalent of the fraction.
